4225 results about "Carboxylate" patented technology

A carboxylate is the conjugate base of a carboxylic acid. Carboxylate salts have the general formula M(RCOO)ₙ, where M is a metal and n is 1, 2,...; carboxylate esters have the general formula RCOOR′ (or RCO₂R′). R and R′ are organic groups; R′ ≠ H.

Dimerized alcohol compositions and biodegradible surfactants made therefrom having cold water detergency

There is provided an alcohol composition obtained by dimerizing an olefin feed comprising C6-C10 linear olefins to obtain C12-C20 olefins, followed by conversion to alcohols, such as by hydroformylation. The composition has an average number of branches ranging from 0.9 to 2.0 per molecule. The linear olefin feed preferably comprises at least 85% of C6-C8-olefins. The primary alcohol compositions are then converted to anionic or nonionic surfactants, preferably sulfated or oxyalkylated or both. The sulfated compositions are biodegradable and possess good cold water detergency. The process for making the dimerized primary alcohol comprises dimerizing, in the presence of a homogeneous dimerization catalyst under dimerization conditions, an olefin feed comprising C6-C10 olefins and preferably at least 85 weight % of linear olefins based on the weight of the olefin feed, to obtain a C12-C20; optionally double bond isomerizing said C12-C20 olefins; and converting the C12-C20 olefins to alcohols, preferably through hydroformylation. The process is preferably a one-step dimerization. The homogenous catalyst comprises a mixture of a nickel carboxylate or a nickel chelate, with an alkyl aluminum halide or an alkyl aluminum alkoxide.

Isoreticular metal-organic frameworks, process for forming the same, and systematic design of pore size and functionality therein, with application for gas storage

The ability to design and construct solid-state materials with pre-determined structures is a grand challenge in chemistry. An inventive strategy based on reticulating metal ions and organic carboxylate links into extended networks has been advanced to a point that has allowed the design of porous structures in which pore size and functionality can be varied systematically. MOF-5, a prototype of a new class of porous materials and one that is constructed from octahedral Zn—O—C clusters and benzene links, was used to demonstrate that its 3-D porous system can be functionalized with the organic groups, —Br, —NH2, —OC3H7, —OC5H11, —H4C2, and —H4C4, and its pore size expanded with the long molecular struts biphenyl, tetrahydropyrene, pyrene, and terphenyl. The ability to direct the formation of the octahedral clusters in the presence of a desired carboxylate link is an essential feature of this strategy, which resulted in the design of an isoreticular (having the same framework topology) series of sixteen well-defined materials whose crystals have open space representing up to 91.1% of the crystal volume, and homogeneous periodic pores that can be incrementally varied from 3.8 to 28.8 angstroms. Unlike the unpredictable nature of zeolite and other molecular sieve syntheses, the deliberate control exercised at the molecular level in the design of these crystals is expected to have tremendous implications on materials properties and future technologies. Indeed, data indicate that members of this series represent the first monocrystalline mesoporous organic / inorganic frameworks, and exhibit the highest capacity for methane storage (155 cm3 / cm3 at 36 atm) and the lowest densities (0.41 to 0.21 g / cm3) attained to date for any crystalline material at room temperature.
